I have a story in mind that has a main antagonist, which is more like a force of nature that will be faced at the end, and another enemy that provokes the inciting incident and will be the enemy for most of the second act, maybe even into part of the third, I'm still not sure about that. But anyway, it should be defeated before the real ending, the final.battle with the biggest threat. Won't this break the rythm? Maybe I should make the main threat grow to keep the stakes and the attention high? I'm worried that if the antagonist that we spent most of the time with is defeated, and there is still a whole act, it will cause a loss of interest
